Generally speaking, the apparatus comprises a spraying device, in connection with means for storing disinfectant liquid, the

means being such as maintain .the device in operative condition under varying condi tions, additional means' being provided to y furnish an air jet periodically to the sprayer to eject the disinfectant liquid. Further advantageous features of'iny device contemplate the improvement of devicesv of this 'class in general, and also contemplate the provision of improved fillingdevices to restore the apparatus `to its initial operative condition, after the supply of liquid has fallen low or become exhausted.

more clearly explained.

Whenever the door is opened or closed, an air jet passes throughfthe sprayer, and drawing disinfectant liquid therefrom sprays the surrounding parts. The details ofthe sprayer whichl prefer to employ are more clearly set forth in Fig. 2, in 'which l have illustrated a T-shaped tube 7, closed at its lower portion by a cap 48, which cap foi-ins a supply chamber for liquid, whose vlevelis indicated'in the illustration. A tube 9, hermetically sealed by virtue of the iniperial coupling comprising the wedgeshapedmember 10 and cap 11, is utilized to permit the entrance'into the sprayer of the air tube 3, which forms at its left-hand extremity an air jet whenever the door check is operated by the door 2. A second tube 12, leading to the controlling mechanism 6, also enters through the tube 9, andhas itslower end immersed in the liquid inthe cup 8. A further tube 13 has its lower extremity iinmeised in the saine liquid, and has a small opening 14 at its opposite extremity, directly underneath the air jet. These two tubes 3 and 13 leave the interiorof the spraying device through the end portion 15. A'hood '16, which, in this instance I prefer to call a nozzle, covers'the extremities of the tubes 3 and 13, and prevents injury thereto. The interior of the T-shaped tube 7 is under atmospheric pressure.

The controlling apparatus (i consists preferably of a main reservoir, comprising an upturned receptacle 17, having its open mouth at the lower extremity thereof, at the neck 18, which main reservoir 17 pro jects into what I prefer to call an aux iliary reservoir 19. These main and auxiliary reservoirs are mounted, through the agency of the improved bracket arrangement, shown more clearly in Fig. 3, although this illustration is on a much larger scale than the apparatus shown in Fig. 4.

This bracket construction comprises an upper bracket member 20, whose upper end engages a recess 21, provided in the top of the main reservoir, and a second bracket member 22, designed to enter the recess 23, on the bottom face of the auxiliary reservoir 19. Between the two bracket members 20 and 22, I provide a channel Vinember 24, which has offsets, corresponding to ears, provided upon the members 20 and 22, so that these members may cooperate 1n holding the device in place.

In the preferred method of mounting the apparatus, the bracket 2O is first secured to the wall' by means of screws 25, whereupon the channel member 24C is mounted in place, then the main and auxiliary reservoirs, 17, 19, and thereafter, the bracket member 22 is mounted in place and screwed to the wall by means of screws 26.

The main reservoir is closed, except at its mouth, which projects within the reservoir 19. This auxiliary reservoir, however, has communication with atmospheric air. Liquid is provided in the main reservoir 17, such liquid being shown at a given height in the illustration, and this liquid slowly finds its way into the auxiliary reservoir 19, remaining at the level indicated, namely, the bottom of the neck 18, and no air can enter the main reservoir 17, except as the level of the liquid in the auxiliary reservoir 19 falls belon7 the lowermost portion of the neck 18. The tube 12, it will be seen, enters through a recessed portion 27, provided in the receptacle, forming the main reservoir 17, and extends down into the liquid within the auxiliary reservoir. This tube 12, it will be remembered, also ext-ends into lthe liquid within the cup 8, and the tube 12 is arranged in the form of a Siphon, in order to maintain the level of the liquid in the cup 8, at the same level as the liquid in the auxiliary reservoir 19.

The operation of the device thus far will be apparent. Liquid is maintained at a given level in the sprayer, through the operation of the main and auxiliary reservoirs 17 and 19, and the supply chamber within the cup 8, and whenever a jet of air is blown through the tube 3, liquid is sprayed from the sprayer, and this liquid again replenished from the auxiliary reservoir 19, whereupon air enters through the neck 18` into `the main reservoir 17, allowing the liquid therefrom to drop, and maintaining the level of the liquid in the auxiliary reservoir 19. It will be seen from this illustration that 1 provide a large air space above the liquid in the auxiliary reservoir, which large air p space allows for the contraction and expans'ion of the air and liquid in the inclosed portions of the device, thus to prevent overowing or improper action of the device.

ln order to fill the main reservoir, l'. provide a tube 28, which extends t0 very nearly the top of the main reservoir 17 This tube 1s designed for connection to a pump as will be more clearly explained hereinafter.`

ln order to supply liquid at the same time the air is being exhausted, l provide a tube 9,9, vvh1ch extends down into the reservoir to a place a short distance above the level of the liquid, and which tube 29 is also adapted for connection with a pump,.as may be explained hereinafter. A hole 30 is provided in the tube 28, which hole permits liquid from the auxiliary reservoir 19 to enter said tube, thereby to prevent air from entering the main reservoir 17 through said tube 28, after the device has been filled, the entrance of which air would permit the liquid from the main reservoir to flow from said `main reservoir totheauxiliaryreservoir and thence overflow. This aperture 30 therefore accomplishes a very useful and highly beneficial purpose in thus sealing the device.

The apparatus herein shown is lled by withdrawing the air from the vessel 17 and supplying liquid to the same. This may be done by any suitable apparatus, a convenient form of which is shown in my Patent No. 1,070,681, issued August 19, 1913,
